ILLINOIS, ASSIGNOR T0 CHICAGO SIGNAL COMPANY,

OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

SELECTIVE SIGNAL-TRANSMITTER.

To all whom it may concern: v

Be it known that I, MAURICE LEVISON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usei'ul Improvements in Selective Signal-Transmitters, of which the following is a specification.

My invention relates to nnprovements in selective signal transmitters and has for its ,impulses indicating differentnumber signals,

instead of using a different transmitter, or different transmitter-wheel, for each signal. Oneof the objects of my invention is to provide a device of the character described which will be small, compact, simple, and not liable to get out of order.

'Another object of my invention is to provide a device of the character described in which the transmitter, when started in signaling operation normally operates to trans mit its set signal a plurality of times, but wherein the transmitter may be stopped after any round of its, operation, the stop always occurring after the completion of a round of signals, so as not to interrupt the transmission of a full signal on any round.

In the drawings wherein I have illustrated an embodiment of my invention Figure 1- is a plan view of the transmitter with the cover removed; Fig. 2-is a side elevation of the transmitter with the cover-removed; Fig. 3 is a small plan view of the complete device; Fig. 4 is a transverse section taken on line 4t4 of Fig. 2; with the cover in place; Fi 5 is a horizontalsection on line 55 of Fig. 6; Fig. 6 is a vertical sectional view taken on line-6+6 of Figs. 1 and 4; Fig. 7 is an inverted plan view of the top plate, showing the movable contact arm in relation thereto; Fig. 8 isa detail view of the adjustable se-' lector members in one relation; Fig. 9 is a diagram of the circuit connections.

In the drawings, the circular bottom plate 15 carries an insulating ring 16 andfour vertical posts 17 of a frame the upper mem- Specification of Letters Patent.

leer of which is provided by a horizontal insulating plate or base 19. Between these upper and lower plates 15-49 is mounted a motor structure 20, to be described, serving to drive an arm 21 mounted on a. central shaft, said arm bearing at its extremity the contact finger 22 pressed upwardly by a spring 23 so as to contact with the under face of the insulating plate 19, and with certain fixed contacts carried bylsaid plate.

Upon the plate 19 in the path of movement of the contact finger 22 I arrange groups of contacts, of which two are shown at 25 and 26, t-hese representing respectively the tens group and the units group. Each of these contacts, as is best shown in Fig. 6, comprises I a pin 27 and a head 28, the pin extending through the insulated plate 19 so thatits lower surface lies in a path of movement of the movable contact 22, and the head providing a spring bend 29 and a transversely folded crest 29 each stationary siderable resiliency. For convenient cooperation on different arcs with the selector parts to be described the heads of the contacts of the tens group, 25, are turned ra dially outward and those of group 26 radially inward with respect to the are on which all of the pins 27 are placed, so that the heads of contacts are at a greater distance from the center of the device than those of contacts 26. Upon the plate 19 I mount two adjustable selector parts, one for each group of contacts 25 and 2G, and each movable to make electrical contact with the heads of any desired number of said stationary contact parts.

Specifically 30 indicates a shaft mounted centrally of the insulating plate 19. On this shaftare mounted for rotation the two movable selector members 31 and 32, arranged independently to be oscillated. One of these members 31 is shiftable to make contact with the heads of any desired number of the contacts of the units group 26 and the other, member is similarly shiftable for electrical so that the upper port-ion of contact member has conconnection with the heads of any desired number of contacts in the group 25 or tens group. As diagrammatically shown in Fig. 9 these two shiftable selector members 31 and are electrically connected with the same side 33 0 a line circuit (shown conventionally as a cell-circuit) and the movable contact. point 22 is electricallv connected with Hitii'i cont: of con oaiiy @0151 0, into thirougi Huf oii; thh SUiLCtUlS t mnootiim oif tho iiui'i'imiont i o "H" 53.13 and 36' are n. .ithui one I tho motor tonne mini tho othoi' oon- 501 m: t o 1; own; oil? a oontaot .oii t] a ton pinto is hit tho it (iiainotw with a 3.

This rocks the shaft 92, throwing the brake out of contact with the disk 87 on the governor and also drawing the controller arm 94 out of the notch in its disk 95 whichis on the contact carrying shaft 82. /Vhenthe latch is thus moved its locking arm 93 is engaged by a catch 99 pivoted on the frame, said catch having a releasing arm 100 which extends over into the of a pin 101 carried by the Wheel 77 which moves in fixed ratio to the gear 76 of the winding lever 75. The parts are so proportioned that shaft 82 receives a predetermined plurality of rotationssay six in numberwhile the pin 101 on gear 77 is moving from its initial position,-taken when the winding lever 7 5 is moved to fully wound position, to the position in which it trips the latch 99 to disengage it from the locking arm 93. The pin 101 releases the catch 99 just before notch 96 registers with the controller arm 94:. Consequently it will be apparentthat when the motor is fully wound and arm 97 throws the brake out of cooperation with the disk on the governor shaft the motor may run its full course to turn the shaft 82 six times before the pin 101 trips out of the latch 99 and permits controller arm 94 to fall in the recess 96 thereby allowingspring 91 to force the brake 90 against the governor disk to stop the motor.

It is desirable that the operator may be pleasure, subject however to the motor completing the then current cycle of rotation of the shaft 82, in order that no signal in course of transmission shall be abbreviated. To this end I provide on the catch 99 a second releasing arm 103 having an inclined surface 104: with which cooperates a vertical plungerv 105 extending upwardly through the'top of the casing and normally retained in raised position by the spring 106, After the operator has wound the transmitter and has started it in motion the plunger 105 may at any time be depressed, its loweractive end acting on the inclined surface 104 to force over the latch 99 to such position that itreleases arm 98. Spring 91 thereupon forces the controller arm 94- into contact with the periphery of the disk 95, but the'torque of shaft 82 is so great that this pressure has no noticeable effect. The motor continues to operate until the completion of a cycle of rotation of arm '21 when not ch 96 re isters a ain with the controller 94- and said arm, dropping into said notch, allows the brake to be thrown into contact with the disk 87 of the governor.

In resume it will be seen that as the operator turns the knob 1'5 to bring the tens numerals 1,2, 3, 4, successively into View at the tens opening 61 in the cover plate, the

selector 'member 32 will correspondingly have its downturned flange moved counter- (Fig 3) to wind the motor,

between rounds if so desired,-so

clock-wise overthe heads 28 of contacts in group 25 to connect one, two, three, or four,as the case may be,-of the contact points of said tens group in electrical connection with binding post '30 for one side of the signaling line and then as the operator moves the other knob 41 oppositely or clock-wise the selector vanced to make electrical connection between the same side of the signaling. line and the heads of a number of contacts of units group 26 corresppnding with the numerical indication displayed through the units opening 62 of the casing. Accordingly, to set the signal, the operator has only to move the knobs to display the desired numbers. The operator then throwsthe handle 75 from dotted line position to full line position which, in the exemplification shown, will rotate the contact arm 22 six times before the motor automatically stops During each rotation of the contact'arm 21 its contact point travels over all of the pins 27 exposed on the under surface of the insulating plate 19, but only those pins whose heads 28 are connected in circuit by the selector plates 31 and 32 are live and accordingly the line circuit will be closed and opened appropriately to send that number signal which indicated by the setting of the instrument. It will be apparent that the number signal will be repeated six times if the motor be allowed fully to run down, but since the parts em; ployed to set the signal are not rotated, and a considerable interval of time 'elapses be tween the completion of one signal round and the commencement of the next, it is easy for the operator to change the setting that a different signal may be set for each signal round if desired. Furthermore when a signal has been repeated asmany times as the operator thinks necessary, less than the total number, the operator may .stop the motor operation at the completion of any then current signal round by depression of the plan ger 105 the operation of which to stop the motor has heretofore been. described.

lVhile I have herein described in some detail a particular tion which I believe to be advantageous in many of its details, and some details of which I may therefore claim, I do not desire to be understood to limiting my invention to the specific construction described further than is specified in the claims and it will be apparent to those skilled in the art that many changes might be made in the embodiment of my invention without departure from the spirit and within the scope of the appended claims.

,VVhat I claim is:

1. In a transmitter of the-character described, the combination of a frame bearing l l l member 31 will be adembodiment of my inv'enthrough a predetermined plurality of cycles, mot or stopping means, means automatically controlling said motor stopping means, to permit its operation only. at the completion of a cycle of operation of the circuit closing means, for latching said motor stopping means in disabled position, means controlled by the mbtor automatically to move said motor stopping means to latched position and to release the latch, and manual means for releasing said latch.

9. In a transmitter of the character described, the combination of a plurality of stationary contacts normal-1y disconnected from a circuit, a movable contact for connection in a circuit, means for moving said movable contactthrough several cycles, on each cycle successively to connect it with the several stationary contacts, means for stopping said motor at the conclusion of any cycle, and selector means for connection in said circuit, cooperating with said fixed con tacts and movable to connect in the circuit any selected number of said contacts.

' 10. In a transmittef of the character scribed, the combination of two groups of fixed contacts, a movable contact, means for moving said movable contact into successive connection with all of the fixed contacts, se-

In testimony whereof I hereunto set my hand in the presence of two Witnesses.
